If a class has no parent ('''very''' infrequent) or if a class has only one parent (very common - this is single inheritance) then the MRO computation is trivial. The MRO of a root class is a list of the class itself. The MRO of a class with one parent is the parent's MRO with the child class added.19 In most cases, C3 can be avoided.
